}
菜单的xml文件如下所示：这个是我从别人的博客中摘抄的。

<?xml version="1.0" encoding="utf-8" ?>

<Menus>

</MenuItem>

</MenuItem>

<FormName>frmInputBooks</FormName>

<ImageName>crest16x16.gif</ImageName>

</MenuItem>

</MenuItem>

</MenuItem>

</MenuItem>

<Text>买sss管理</Text>

<FormName>frmBuyBook</FormName>

</MenuItem>

<Text>dsafasdf</Text>

<FormName>frmBuyBook</FormName>

</MenuItem>

</Menus>
下面来说明一下XML文件。
Text：为显示在窗体上的文字，
ItemID：为菜单的ID，
ParentItemID：为此菜单的父菜单ID如果是顶级菜单则为0
FormName：为单击菜单所要显示的窗体类名如果是还有下级菜单的则不要写。
IsModule：是否还有子菜单1有，0没有
Level：菜单所在的层数。目前还没用到。
ImageName：菜单前的图标为16x16的图片文件，这个我这里没有用到

在这里还可以根据自己的需要加其它的属性，也可以写成以数据库的方式。
这是我目前用到的功能。我会继续发表我做这个小软件的心得体会。希望对大家有所帮助。
